Product Uses

It is not only suitable for the freeze-drying of bulk (liquid, paste, solid) conventional substances but also for the drying of substances packaged in vials. During the freeze-drying preparation, materials can be portioned into vials as needed, sealed with bottle caps, and then subjected to freeze-drying. After drying, the stoppering device can be used to tightly seal the vial caps. This process helps prevent secondary contamination and reabsorption of moisture, making it easy to store the materials for an extended period.


Product Operate Guide

The control system of this machine features a large touchscreen, providing convenient, straightforward operation with powerful functionality. Each screen displays a wealth of data in an intuitive and clear manner. It can store hundreds of temperature control programs, with each program allowing for the configuration of up to 36 segments.

Advanced fuzzy PID control algorithms ensure precise and stable temperature control. During automatic temperature control, you can modify temperature parameters and skip segments as needed, offering flexibility in operation. The system controls shelf temperatures according to pre-set parameters. Multiple stability measures are incorporated into the system, ensuring stable and reliable operation.


FAQ

1. What is a stoppering freeze dryer, and how does it differ from other freeze dryers?

A stoppering freeze dryer is a type of freeze-drying equipment that is designed specifically for sealing containers, such as vials or bottles, after the freeze-drying process. It differs from other freeze dryers in that it includes a stoppering mechanism to create a hermetic seal on the containers, preserving the integrity of the dried product and preventing contamination. This feature is particularly valuable for pharmaceutical and biotech applications.


2.What are the advantages of using a stoppering freeze dryer?

The main advantage of a stoppering freeze dryer is its ability to provide a sealed container for the dried product. This is crucial for maintaining product stability, preventing moisture reabsorption, and ensuring product integrity. It is commonly used in industries where product quality and long-term storage are critical, such as pharmaceuticals, biotechnology, and food.


3. Can a stoppering freeze dryer be used for laboratory-scale applications?

Yes, stoppering freeze dryers are available in various sizes, including laboratory-scale models. These smaller units are ideal for research and development purposes, allowing scientists to conduct experiments and develop freeze-drying processes while maintaining the benefits of container sealing. They are commonly used in pharmaceutical research and biotechnology laboratories to optimize formulations and ensure product quality.
